Abstract
The utility model relates to a transformer anti-theft device which is mainly used for prompt alarm when a power transformer or a power cable working outdoors is stolen, or in an open-phase or power-off state. The transformer anti-theft device particularly suitable for the anti-theft works at the beginning of transformer station construction adopts the structure that the normally closed contact of an AC contactor is connected with an electric whistle, a switch and a power supply sequentially to form a DC circuit, and the plug of the AC contactor is connected with AC voltage. The transformer anti-theft device has the advantages of novel concept, unique design, simpleness in manufacture, low cost, high safety and reliability, strong practicability, convenience in installation and placement, small occupied area, compact structure, easiness in operation, convenience in maintenance, and high performance-price ratio.
Description
Technical field
The utility model relates to a kind of anti-theft device, relate in particular to a kind of anti-theft device for transformer, be mainly used in power transformer in the outdoor occasion work and power cable and run into the timely warning of stolen, phase shortage and powering-off state, be particularly suitable for the antitheft work during transformer station just builds, belong to the electric power application.
Background technology
Because the management imperfection, and interim institute was far away with the transformer station distance, when the guard personnel have fatigue " doze " certainly, is unavoidable if do not take effective precautionary measures house transformer stolen during transformer station just built; Will cause the tremendous economic loss.
Summary of the invention
The utility model provides a kind of anti-theft device for transformer at above-mentioned problems of the prior art, has solved the problem that substation transformer of the prior art is lost easily, and the utility model is safe and reliable, and cost is low, easy accessibility.
The technical solution of the utility model is as follows:
The normally closed contact of A.C. contactor constitutes DC loop with electric whistle, switch and power supply successively; The plug of A.C. contactor links to each other with alternating voltage.
Described power supply is a button cell.
The utility model has the advantages of as follows:
1, show an interesting new approach, design is unique, makes very economical simply again.
2, the safe reliability height is stopped the phenomenon of hurting sb.'s feelings.
3, practical, small and exquisite, to put easy for installationly, floor area is minimum.
4, compact conformation, easy operating, easy to maintenance, the cost performance height has promotional value and application prospect widely.

Fig. 2 is a principle wiring schematic diagram of the present utility model.
Among the figure, TV, field coil, E, button cell, ZJ, A.C. contactor, L, electric whistle, B, normally closed contact, K, switch.
Embodiment
The utility model in conjunction with specific embodiments, is described in detail as follows with reference to accompanying drawing.
Embodiment
The normally closed contact of A.C. contactor constitutes DC loop with electric whistle, switch and button cell successively; The plug of A.C. contactor links to each other with alternating voltage.
Technical indicator:
1, electric whistle resistance-8 Ω;
2, environment temperature :-20～50
0C;
3, ambient humidity: be not more than 80%;
4, alternating voltage: 220 ± 10%V;
5, DC voltage: 6 ± 0.4V.
Principle of work of the present utility model and process are as follows:
When the plug of A.C. contactor was inserted in the 220V supply socket, the normally closed contact of A.C. contactor disconnected; When if AC dump takes place, the normally closed contact of A.C. contactor is closed immediately, and DC loop is connected, and the emergency alarm bell sound of electric whistle rises.
Claims (2)
1. anti-theft device for transformer is characterized in that the normally closed contact of A.C. contactor constitutes DC loop with electric whistle, switch and power supply successively; The plug of A.C. contactor links to each other with alternating voltage.
2. anti-theft device for transformer according to claim 1 is characterized in that described power supply is a button cell.
